FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part ofLetters Patent No. 228,523, dated June 8, 18.80.

Application'led April 16, leso. (Model.)

To all whom it may concern:

Be it known that I, ALBERT E. FRENCH, a citizen of the United States, residing at Detroit, in the county of XVayne and State of Michigan, have invented certain new and useful Improvements in Fasteners for Meeting- Rails of Sashes; and I do hereby declare the following to be a full, clear, and exact description of the invention', such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or igures of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in the class of sash-locks for the meeting-rails of window-sash, and it consists in two plates pivoted together at their center, one of which is stationary, the other made to turn on the central pivot, each provided with an annular iiange 011 its inner face, made to lit one within the other, whereby an inclosed chamber is formed between the plates for the reception of suitable lookin g mechanism, and the movable plate having rigidly Xed to its outer face a bar or bolt whose motion is governed by the plate to which itis joined; also, in certain other details of construction, hereinafter more fully described and shown.

In the drawings, Figure l is a perspective view of my invention. Fig. 2 is a plan view of same. Fig. 3 is a side elevation, showing the bar in position. Fig. 4L is an end view. Fig. 5 is a horizontal section through the line .r .r of Fig. 4, showing the interior construction. Fig. G is a vertical section through the line y y of Fig. 5, showing the central post or pivot. I

A is the main plate, which is provided with suitable screw-holes for attaching it to the sash, and having the annular flange B and central post, a. p

G is a iat bolt resting upon the plate within the flange, an elongated opening being provided in its center, through which projects the post c, and which permits the bolt to move freely back and forth. Its movement is regulated and limited, and it is kept in place by small projections or posts F, insertedfin the plate at its side and end, and a flat spring,D, occupying the outer circumference of its central opening around post a. Its smaller end projects through a recess in iange B.

o is a recess in the side of the bolt for the accommodation of the blade or bit of a key by which the bolt is actuated.

E is the'upper or outer disk, which is united to, or cast solid with, the bar e, and is also provided on its inner face with a iiange or rim of suflicient diameter to inclose iiange B of plate A when placed in position over it. A recess is provided in this iiange, into which fits the end of bolt C when shot forward, as shown in Fig. 5.

G is a projeeting'pin on the side of bar c, to prevent said bar being turned from the outside by the insertion of any instrument between the sash.

My device is operated as follows: It is rmly attached to the top rail of the lower sash of a window by screws through plate A. The disk E is then turned so that the projecting end of bar e is beneath hook K on the bottom rail of ,the upper sash. It is then locked in position by inserting the key through the key-hole p, when the bit or blade of the key occupies the recess o in the side of bolt C. The key is then turned forward, causing the bolt G to slide forward, so that its end passes through the slot in iiange B into recess H of the outer iiange, thus holding disk E firmly in place, so that it cannot turn on pivot a until released by reversing the movement with the key. The projection G on the side of bar e is designed to prevent the bar from being turned from the outside when not locked by inserting the blade of a knife or other similar instrument between the sash and bearing against it.

It is obvious that any instrument inserted between the sash and interposed between the hook K and projection G would be tightly clamped between the two by any lateral pressure upon bar c, and the resistance would increase in proportion to the pressure exerted.

In order to prevent my lock ybeing taken apart, the top of post e may be riveted, instead of uniting the parts by a nut or screwhead, as shownin the drawings.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isl l. In a sash-lock, the xedflanged plate'A,

The plate A, having the recessed flange B, central post, a, and studs F, the sliding' bolt C, arranged within the iauge and between the guide-studs, to be actuated by a key, in combination with the recessed hanged disk E, pivoted to the central post, and provided with the bar e, rigidly attached thereto, substantially as and for the purpose set forth.
